PORTFOLIO WITH DETACHABLE MAILING CARD Filed Sept. 14, 1960 'lll/ll y INVENTOR BY *XM/mn ATTORNEYS 341252332 PRTFH W111i DETACHABLE fi/.lALlNG CARD Wilton .'i. Luhe/ack, 791 Seneca St., Buffalo, NX. Filed. Sept. 14, 196i?, Ser. No. 55,915 i claim. (ci. 22a- 72) The present invention relates to a portfolio with detachable mailing card and constitutes a continuation-inpart of my copending application for Portfolio Made of Paper, Serial No. 807,792 tiled April 21, 1959.

Generally the present invention consists of an identical structure with that shown in `my aforesaid copending' application with the addition of a removable mailing card detachably secured to the inner side of the completed portfolio.

It accordingly is the principal object of the present invention to provide an inexpensive detachable mailing card which may be formed as a part of a portfolio as above set forth.

Another object of the invention is to provide a detachable mailing card in a portfolio formed of a single, printed die cut sheet.

A further and important object of the invention is to provide a device of the character set forth which may be manufactured and printed simultaneously and from the same blank which forms the portfolio above referred Other and further objects of the invention will become apparent from a reading of the following speciication taken in conjunction with the drawing, in which:

FIG. 1 is a plan view of the reverse side of a diecut paper blank showing the score lines along which the blank is to be folded and also showing the areas to which glue is applied for sealing the portfolio as a part of the folding.

FG.- 2 is a plan view of a completed portfolio embodying the invention, viewed from the inside thereof.

FlGS. 3, 4 and 5 are enlarged fragmentary sections taken onthe correspondingly numbered lines of FlG. 2.

FIG. 6 is a perspective view of a partly opened completed portfolio showing, in dotted lines, the manner in which the pockets can be used to contain papers or other materials.

To provide a low cost portfolio an important feature of the invention is that it is made from a single sheet 1d of paper which is diecut to form the blank illustrated in FlG. l and is also provided with score lines as hereinafter described to facilitate folding the blank into the form of a portfolio. The paper sheet 1li is preferably of high quality paper having high tear and burst strength with minimum hygroscopicity and there can be imprinted thereon any desired ornamentation or useful blanks or data (not shown). The blank sheet 1t) has four score lines 11, 12, 13, 14 defining a rectangular front cover panel 15 and has four score lines .13, 16, 17 and '1S delining a rectangular rear cover panel 19, the score line 13 being common to both panels and providing the hinge in opening and closing the portfolio.

The line 17 also forms one margin of a relatively wide flap 2li which forms a vertical side pocket along the outer edge of the rear cover panel 19. The longitudinal free edge 21 of this flap forms the mouth of this pocket and its shorter edges 22, 23 preferably converge toward the outer edge 21 to facilitate the folding and gluing operation.

The score line 14 and adjacent part of the score line 18 form one margin of the relatively wide portion 25 of a tlap, which relative wide portion forms a bottom pocket for the front panel 15 of the portfolio, the free longitudinal edge 2.6 of this llap forming the mouth of 3,082,932 Patented Mar. 26, 1963 "ice the pocket. One side of this pocket is provided by an edge 28 which preferably converges outwardly with reference to the hinge A13 of the portfolio. The remaining margin of the flap 25 is formed by a score line 29 which forms a continuation of the hinge line =13 but is arranged at an angle to this hinge line. This angularity is in the order of 3 with reference to the hinge line 13 toward the edbe 28 of the flap 25. This particular angularity has been found essential in providing a bottom pocket closed on three sides and which lays flat when the portfolio is closed along its hinge line 13.

The relatively wide portion of the flap Z5 is continued beyond the score line 29 to provide an extension 30` extending transversely of the flap and to provide a relatively narrow extension 31 projecting along and forming a narrow flap at the bottom of the back cover panel 19. The extensions or aps 30 and 31 are .provided with the stripes or layers 32, 33 of glue or other adhesive, this adhesive being on Ithe back of the blanks.

The blank includes a single relatively narrow top flap 34 extending outwardly from the score lines 12 and 16 and forming a com-mon upward continuation of the front and rear panels 15, 19 of the portfolio. This outward extension 34 is provided, on the reverse face of the blank, with a stripe or layer 35 of glue or other adhesive.

The paper blank is completed by a relatively narrow side ap 38 projecting outwardly from the score line 11 and forming a continuation of the front panel l15 of the portfolio. rhis extension is provided, on the reverse side of the blank, with a stripe or layer 39 of glue or other adhesive.

An outer clearly transparent layer, lamina or sheet itl made of plastic is provided on the paper blank 10 which is smooth and glossy, has high tear strength and is highly resistive to moisture, scuing and abrasion and which extends around all marginsof the portfolio. For this purpose this clearly transparent plastic lamina 40 extends part way across the relatively narrow ap 38 as illustrated at 41 in FIGS. 2 and 3 and this clearly transparent lamina also extends part way across the relatively wide side pocket flap 2.0 as 4illustrated at 42 in FIGS. 2 and 3. This clearly transparent plastic lamina also extends across the relatively narrow top flap 34 as illustrated at l43 in FGS. 2 and 4 and this lamina also extends across the relatively narrow portion 31 and part way across the relatively wide portion 25 of the bottom ilap as indicated at 44 -in FIGS. 2 and 4. The clearly transparent layer or lamina 4t) covers the -entire obverse faces of the front and rear cover panels 15 and 19 and strengthens the hinge connection 13 between these panels.

With the blank formed and'glued as shown in FIG. 1 and as above described the blank is folded as follows, this being done in a conventional folding machine as a continuous operation.

The relatively wide side pocket flap 2t) is first folded along the fold line 1'7 to bring it against the inside face of the rear panel 19. The relatively wide bottom pocket portion 25, together with the relatively narrow portions Si), 31 which jointly form the bottom ap is then folded along the fold lines 14, 18 and its glue 32 and 33 broughtA into adhesive relation with the inside face of the back panel 19 and also the face of the llap Ztl. The top flap 34 is then folded along the fold line 12, 16 so as to bring its glue facing 35 into adhesive relation with the inside faces of the front and rear panels 15, 19 as well as with the relatively wide side pocket flap 20. The llap 38 is then folded along its fold line 11 so as to bring its glue facing 39 adhesively into contact with the inside face of the front panel 15 as well as with the flaps 25 and 34.

3 When this is done, by virtue of the fact that the fold line 29, while a continuation of the hinge line 13, but being at a slight angle thereto, the pocket formed by the flap 25 does not bulge or distort when the portfolio is folded along its hinge 13. t

It will be noted that in the completed portfolio the plastic lamina 40 extends around all four edges of the portfolio as indicated at'41, 42, 43 and 44 so as to form a reinforcement at these edges. It will also be noted that the flap 20 forms a deep side pocket for the back panel 19k which pocket is of substantially thesame length as the panel 19 and will hold articles with little danger of loss since it has been found normal to open the portfolio in the manner of a book, that is, with the rear panel 19 being left on the surface of the table and the front panel lifted. uforms a bottom pocket on the front panel 15 of the portfolio which securely holds any papers placed therein against loss under any normal carrying condition of the book. At the same time the portfolio is of very low cost, while at the `same time having outstanding wearing qualities and usefulness.

All of the above descriptive matter pertains to that por-k tion of my invention which isincluded in the aforesaid copending application. Y

The present invention comprises a rectangular mailing card 50 one of whose longer edges is formed integrally with the lower edge of the relatively narrow bottom flap portion or extension 31, as viewed in FIG. l. The card 50 is detachable from the extension 31 by a perforated line 51. One of the shorter sides of the card Sti abuts the free adjacent edge of the extension 3G as indicated at 52. In the course of printing of the portfolio as above set forth, it will be apparent that the card 50 may likewise be printed simultaneously therewith and may contain, for example, upon one side thereof a printed address 53 while upon its other side there may be printed matter including blank lines 54, for example, for the placing thereon ofa return address.

It will be readily apparent that the portfolio in its assembled condition as above described'will present upon the inner side of its back cover, as clearly indicated in FIG. 6, the card 50 whichextends in the same plane as the extension 30 and the extension 31 but which is readily severable therefrom by folding the same alongtthe perforated line 51 one or two times and then tearing the same from the extension 31.

It will be apparent that printed matter such as advertising or the like may be placed upon the flap 25 and conveniently utilized in connection with the card 50.

While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that minor modifications may be made Without departing from the spirit of the invention or the scope of the appended claim.

What is claimed is:

In a portfolio adapted to open like a book (A) a single sheet of paper folded to provide (a) a rst rectangular panel,

(b) a second rectangular panel connected to said rst rectangular panel by a first fold line forming a hinge and said pair of companion bottom edges which form linear continuations of each other across said first fold line,
